[pulseaudio-tickets] [Bug 44777] module-rtp-send floods the network with UDP packets, crippling it severely

--- Comment #16 from Tanu Kaskinen <tanuk at iki.fi> ---
Sending a wav file means a TCP connection between two computers. TCP
connections are the most common type of traffic, and the hardware is optimized
accordingly. UDP multicast is different, and apparently network hardware is not
necessarily as efficient with processing that protocol. Comment #9 seems to
suggest that the wifi specification itself forces multicast to be inefficient,
so it's not necessarily just the hardware's fault.

Starting from PA version 5.0, module-rtp-send should not generate traffic when
nothing is playing (it can still be configured to play silence, but paprefs
doesn't configure the module that way). If you observe different behaviour,
please file a new bug and attach the output of "pactl list".
